When I bought my 2012 x25 it only came with two power tower speakers I recently added two more PowerTower speakers and I'm wondering if I can just connect them to the amplifier that is running the existing two tower speakers or if I need to get a whole new amplifier? Thanks in advance.

What amp are the current pair if tower speakers connected to? The factory sound systems are usually underpowered...so chances are that by adding two more speakers to your factory amp you are going to have even less power to your speakers. Are they JL speakers? The possibilities are endless... Let me know what you have and I might be able to give you a few suggestions. I'm in the process of upgrading my system and have done a fair bit of research and asking questions.

Yes they are JL speakers and amps I will check to see what I have for amps I believe there is two in there.

So there is two JL audio amps in the boat, a big amp and a smaller amp the smaller amp runs the tower speakers and the bigger and runs the sub and the four speakers inside the boat. Thoughts?

you'll need a bigger amp. i believe the small one is like 250 and you need double that

The small amp could be either a 600/4 or a 750/1. Very hard to say by looking at the picture....but my guess would be it's a 600/4. There's a plate on the front of the amp which shows what model it is. The 600/4 is a 4 channel amp which delivers 150W RMS per channel at either 4, 3, 2 or 1.5 ohms. It can be bridged into 2 channels delivering 300 watts per channel...but that's way too much power for the JL speakers. If it is a MHD 600/4, you're in luck! You could add two more speakers so you have a total of four, each getting 150 watts, which is GREAT for the JL speakers.

So if I get another one of the smaller amps and hook up to the other two new tower speakers will that work?

imyourmaster

Aric is right...looking at the pics again... Those are M series amps... The small one is a 400/4 or 200/2 and the bigger one could be a 700/5. So you can be sure your speakers are underpowered.

Dali...before you go any further...find out exactly what the models are of the 2 amps. They are M series for sure.

Thanks Deon I will check to see if I can get the model number. Report back soon.

Ideally, JL recommends driving each of those speakers with 175 watts RMS at the high end of the scope. They peak at 225 watts RMS. The ideal way to accomplish that is by means of a MHD 600/4 or a MHD 750/1

The small amp reads 200–2 and the Big amp reads 500–7

Wow those amps are expensive. 320 for the small one and 600 for the large one on ebay.

The M 200/2 can not drive your JL tower speakers to their full potential...not by a far stretch. So getting another one to drive your second pair is not a great idea. You can spend days researching and you'll come back to the same conclusion...MHD 750/1 or MHD 600/4. Either of these will bring the JL tower speakers to life!

Your 700/5 is also not quite up to the task of driving your in-boat speakers. It seems like a neverending dilemma with MC... They certainly teamed up with a fabulous audio developer, but they keep pairing amps which are not up to the task of delivering the power with their speakers.

It really depends on how you look at it...if a GREAT sounding sound system is something you value and ENJOY, the cost to make it happen will be more than worth it...and only a fraction of the investment you made when you bought your MC.

So the 750/1 will deliver 187 watts to each tower speaker and the 600/4 will deliver 150 watts to each tower speaker? Is the 750/1 a one channel amp and the 600/4 a four channel amp? which one is better for my application?

Probably time to upgrade.

Dali, I'll leave you with this advice for the time being.... Call Odin at Earmark Audio 1-888-393-6789. They currently run an incentive for customers who already own JL Audio equipment. They will take your used JL amplifiers as a trade in on new JL equipment which can save you a lot of money. I bought my MHD 600/4 as part of a package deal with my old JL trade in from Odin at an unbeatable price. He's also super knowledgeable and a stand up guy to be dealing with. Yopu can't go wrong. You also have the peace of mind that they are a truly legit JL Audio dealer along with all the other great brands they carry.

Both are superb amps for your application. The 750/1 is indeed a one channel MONO amp and will deliver slightly more power BUT you will have to connect your four speakers in series/parallel. The 600/4 is a 4 channel STEREO amp and requires straight forward wiring...each speaker has a dedicated channel.

There is an excellent article at Earmark Marine's website which compares the two. with 4 speakers so close to each othe the stereo effect is for all practical reasons null and void. Some guys strongly oppose this idea...

Awesome. Thanks Deon for all the help.Very much appreciated. I will call them tmrw and see if I can trade my 200/2 for the 600/4

If this helps, I'm going to run my 4 towers with an HD750/1...in boat speakers it is o.k. to have lower wattage because the cabin is more enclosed.
